Recent developments in less invasive technology to monitor blood glucose levels in patients with diabetes

Abstract

In this review we discuss recent developments focused on less invasive methods of self monitoring for diabetes mellitus. The gold standard for self monitoring currently involves a small device measuring the blood glucose level in a droplet of blood taken from the fingertip or forearm of a patient. This lancet approach is done on average 3-4 times a day and can be uncomfortable and inconvenient. It is known that monitoring blood glucose more frequently leads to better control and maintaining overall health. However, invasiveness of the finger stick method has caused patients to ignore the need to monitor their blood glucose levels and leave themselves at risk for future complications. One thing absolutely necessary to maintain control over diabetes involves monitoring and regulating blood glucose levels. Without proper monitoring, serious complications can ensue, including cardiovascular disease, end stage renal disease, visual impairment, decreased circulation leading to amputation, and diabetic ketoacidosis.
